Karthi Ratnam
Fractional GTM Leader
Who Karthi works with
Karthi Ratnam is a Fractional GTM Leader for AI and SaaS companies, including startups and enterprise organizations. Karthi is GTM OS Certified, trained in GTM Partners' proven GTM expertise, frameworks, and systems. Her client work targets buyers in Revenue Operations and Growth leadership roles, serving teams at companies like Scalestack, Swan AI, Sprouts.ai, and GTM Buddy.
The GTM problems Karthi solves
Karthi addresses B2B commercial challenges where companies rely on incremental marketing, manual work processes, or lack narrative clarity and category positioning. Rather than operating in isolated silos, Karthi uses the GTM Operating System (GTM OS) to align marketing, sales, and customer success around unified growth engines. Her work focuses on resolving pipeline velocity bottlenecks, eliminating manual work taxes with agent-driven systems, and shifting organizations away from duct-taped go-to-market tactics toward autonomous, scalable revenue systems.
Track record
Karthi brings more than 15 years of experience advising B2B startups through enterprise companies. She is the co-founder of Audience Haus and previously served as Head of GTM at GTM Partners. Her track record includes partnering with founders to design categories, build revenue strategy systems, and coach executives on narrative clarity and the Swan Metric (revenue per employee).
In Karthi's words
I help B2B companies move beyond incremental marketing and step into category leadership. My work blends movement marketing, ontological design, and revenue strategy to create GTM systems that aren’t just effective, they’re transformative.
Why hire Karthi instead of a traditional fractional executive?
Karthi is a GTM OS Certified fractional GTM leader, trained in GTM Partners’ proven GTM expertise, frameworks, and systems. Instead of filling one seat in one department, Karthi works across marketing, sales and customer success, aligns your GTM across the organization, and guides the executive team from diagnosis to execution on the GTM Operating System™.
Capital is no longer cheap. You get senior GTM leadership and a proven operating system without the full-time executive price tag.
You hire the result, not the role.
More than certification
As a GTM OS Partner, Karthi operates inside a franchise-style model with ongoing access to:
- GTMee AI — trained on the full body of GTM Partners IP.
- Coaches & masterminds — peer-led sessions with the GTM Partners expert community.
- Direct access to Sangram & Bryan — the founders of GTM Partners and creators of the GTM OS™.
- Specialist network — they can pull in other certified experts to solve your specific challenge.
- Frameworks, templates & tools — proven playbooks that guide you and your team toward the outcomes you’re after.
Partners pay a monthly or annual license to stay active. They're invested — and they stay sharp.
